Quick search outlook 2021 problem

[santapinki]

Hello everyone
I have a question about searching in outlook.
I am connected to the exchange server.
When I do a search, it searches for letters for 3 days.

today

last search

To make it search more, I need to click
include older results

How can I make it search not only for 3 days, but for a month at once? (without clicking include older results)
Or should it give a full search (include older results)?

The problem has decreased.
In cache mode it always shows only 25 results.
If after searching you click include older results.
It will show 250 results.
How can I change these numbers?
